What this period brings
Rahu's eighteen years amplify desire and put you somewhere unfamiliar — a foreign country, a new field, an unconventional path, or simply a life your family did not expect. Growth is real but rarely linear, and often arrives faster than the ground under it settles.
Where it tends to go well
Anything new, technological, foreign, or outside the establishment. Rahu rewards people who are willing to be beginners in public.
Where it asks for care
Contentment and orthodoxy. The classical caution is illusion — chasing something because it glitters — and the practical one is overextension.
The nine antardashas
Every mahadasha divides into nine sub-periods (antardasha or bhukti), running in the same fixed order and starting with the lord's own. Each is Rahu's 18 years times the sub-lord's share of 120 — so the table below is arithmetic, not opinion. Your own dates depend on the Moon's nakshatra at birth, which the calculator works out.
| Antardasha | Length |
|---|---|
| Rahu – Rahu | 2 yr 8 mo |
| Rahu – Jupiter | 2 yr 5 mo |
| Rahu – Saturn | 2 yr 10 mo |
| Rahu – Mercury | 2 yr 7 mo |
| Rahu – Ketu | 1 yr 1 mo |
| Rahu – Venus | 3 yr |
| Rahu – Sun | 11 mo |
| Rahu – Moon | 1 yr 6 mo |
| Rahu – Mars | 1 yr 1 mo |
How to read this honestly
Rahu is a shadow point, not a body, and its dasha has no fixed sign of its own: it delivers through the house it sits in and the planet that rules it. That is why two people in the same eighteen-year period can have completely unrelated experiences of it.
Frequently asked
- How long is Rahu Mahadasha?
- Eighteen years — the second longest after Venus.
- Is Rahu Mahadasha bad?
- It is intense rather than bad. It amplifies ambition and change, and it delivers through Rahu's house and dispositor in your chart, so it varies enormously between people.
